Re: On-line engine blitz tourney December

KPK evaluation can be kept very simple: identify a small set of standard situations where the outcome is a draw, evaluate these as 0, and let the search do the rest based on material only (no PST). Typical standard draws are (assuming the moving side is not in check, no illegal or stalemate position):
the "(no PST)" was a bad idea of course so remove the phrase "based on material only (no PST)". Otherwise the stronger side might fail to advance the pawn.
must be: non-rook pawn neither on 7th (2nd) nor on 6th (3rd) rank: [...] (to exclude wPc6, wKd6, bKc8 where White to move wins by c6-c7)- non-rook pawn not on 7th (2nd) rank: defender king two squares in front of pawn and attacker to move (e.g. wPc5, bKc7, White to move)
I'm curious about this "AndScacsRB". Someone knows what is? Thankshgm wrote: ↑Sat Dec 22, 2018 11:49 pmCode: Select all

Merry Christmas Daniel !
Nice! As you wish It's difficult for me to be there for the tournament.Modern Times wrote: ↑Sun Dec 23, 2018 10:39 pm Yes it is me. In the past I've run Trace, Crafty, Cheng, Nirvanachess, Gaviota, Stockfish and maybe some others I've forgotten. Graham suggested this time that I run AndScacs. There have been occasions when the author himself has participated, in which case I choose a different engine. There are so many particpants these days it can be difficult to find an engine that isn't already there ! But I've been absent for a while due to other commitments at the time.
